Refrigerated Air Dryers are basically little refrigerators. They chill the air stream causing the water in the air stream to fall out as condensate. Refrigerated Air Dryers generally will give you a dew point of between 39 and 50 degrees Fahrenheit. Dew Point is the temperature in which air cannot carry anymore water. These dryers are generally used inside or in applications that freezing conditions are not present. With SMH High Temp Dryers it is no longer necessary to upsize the dryer compensate for. Schulz SMH High Temp Dryers eliminate the need for separate aftercooler and moisture separators, conserving valuable floor space. This also means less equipment to install and maintain. High inlet temperature or high ambient temperature conditions, Schulz SMH dryers are designed to accept up to 194 F inlet air temperatures and operate in 113 F ambient conditions
